"一个人做一件事情通常有两个理由，一个听起来好听的理由和一个真实的理由。"

Simplified Meaning:

People often have a hidden reason for their actions that they don't share with others. The reason they tell everyone usually sounds nice and acceptable, but the real reason is often more personal or self-serving. For example, a person might say they are working late to help the company, but their real motive might be to get a promotion or a pay raise. In history, a leader might claim they are going to war for peace, but their true reason could be to gain more power or land. This quote teaches us to look deeper into why people do things because the true reason might be different from what they say. In your own life, it's good to be honest with yourself about why you do things and also pay attention to the possible hidden motives of others. This awareness can help you understand situations better and make wiser decisions.
